Japan has become a wasteland devastated by the Rusty Wind which causes all things to rust away. A suspicious looking priest visits a checkpoint all alone, yet on his back rests a bow priests wouldn't use.
Meanwhile, Milo, a doctor running a clinic in the town of Imihama, is researching new medicines in secret in order to save his older sister, Pawoo, who's being corroded by the Rust. But that day a stranger appears before him...
Luckily for you, I'm a man.
لحسن حظّك، أنا رجل
Ein Glück, dass ich ein Mann bin.
Suerte que soy un hombre.
Suerte que soy un hombre.
Heureusement, je suis un homme.
Fortunatamente per te, sono un uomo.
Por sorte, sou um homem.
Повезло тебе, что я парень.
